To all erizo/"12, l1i only Concern:

Be it known that l, lliminmi limone, a subject of the German Emperor, residing at Bloomfield, in the county of Essex and State of New elersey. have invented new and useful improvements in or Relating to Doors `for Coke-Ovens, (zis-Retor'ts, and other Fur- `within the oven charge so to prevent decomposition or same, and 'furthermore to reduce the cooling of the ends o 'the charge nearest the doors, so that. a more nnitorxn distillation of the oven charge over the entire length is effected.

The accompanying drawing illustrates` the application of my improved door to a horizontai coke oven.

@n the drawing Figure l is a longitudinal vertical section through a portion of an oven and the ovendoo-r, whiie Fig. 2 is a horizontal section according to Fig. l, and Fig. 3 illustrates in a longitudinal vertical section through a portion oan oven and door a. differentmethod of carrying the ipresent invention into eiect.

Referring to Figs. and 2, numeral l denotesthe oven or retort chamber and 2 the oven door. lining of the door foi-insa number of passages 3 extending 'from the lower to the upper end the door, and communicating with the oven chai-ober by means oi ducts s. it' wili he seen that the gases evolved in that part orn the oven charge near the door will be drawn through he lover ducts, up the vertical passages and out by the upper ducts into the ilpper'part of the retort, 'from whence they escape in the usual, manner into the ascension pipes 5. To increase the quantity oi' gases withdrawn from Wii'hin the charge through the oven door, openings 6 are provided in the oven door opposite the lower ducts if, which are kept closed by stoppers. llhen Athe oven is charged a rod is inserted 'through these openings and pushed into the oven charge as indicated in dotancl dash lines5 after withdrawal 'of which, clue io the moisture contained in the coal and the iine stite to which thelat'ier is crushed, a permanent passage or channel will he lci in the oven charge which serves to collect the gases and conduct. them to the passages in the oven door. Bv means of the detachable bottoni plate 7 the passages inthe oven easiljg,7 accessible for cleaning, ete. deut that instead of conducting flowing through the passages in door back into the oven chamber,

lt is evithe gases the oven they may of course, loe Withdrawn in any other' suit- 65 able manner.

Fig. 3 illustrates an oven door according' to `this invention butI diering from the one before described. .'1 againdenotes-the oven chamber and 2 the door. As will be seen 7o the door proper 2 is provided with a second inner door or shield 8, which by suitable means, in this ease by the hand-Wheel 9 and screw 10, can be moved a little distance into the oven chamber. this is to forni the vertical passages 3 in Figs. 1 and 2 and which serve for conducting the gases above the coal charge, by the charge itself, or rather by charge and oven door, which iis accomplished f by stowing the coal charge away from the door during' coking. ln this case the inner door 8 can during charging 'of theoven be held in the position indicated in dot and dash lines, so that the coal will lill up against it, and afterward be brought back in the original position; or the inner door during charging may be kept-- in its original position and after charging is comoleted ressed into the oven therebv forming the charge, after which it is broughtl baci; into piace. in this construct-ion as be- 'fore openings 'provided with Stoppers are arranged in the door, through which a rod can be rammed inio the charge so as to form additionai collecting passages.

instead of swinging the inner door into the furnace around a fixed point as in the example given. it may of course, also be Amoved into the oven lateraliy and with 10C* drawn in lhe same manner.

Having now described my invention clare that what l claim is:

l. The combination with an oven or furl denace of the kind described of a door, the

interior ot which forms a passage for gases of distillation, and connections between the said passage and the lower and upper parl: of the oven chamber.

2. The combination with an oven or urnace of the kind described of a door, the interior of which forms an upright passage.
